Julia Letlow Makes History: Louisiana Republicans Choose Trump's Fighter

Louisiana Republicans didn't just pick a nominee on June 27. They set the state on course to send its first Republican woman to the United States Senate, and they did it by rallying behind the candidate President Trump asked them to.

U.S. Rep. Julia Letlow defeated State Treasurer John Fleming in the Republican runoff for U.S. Senate, winning 57 percent of the vote to Fleming's 43 percent. The race capped a bruising few months that began when Trump made clear he wanted Sen. Bill Cassidy gone, a consequence Cassidy earned himself when he voted to convict the president during the 2021 impeachment trial that followed January 6. Cassidy never recovered. He finished a distant third in the May 16 first-round primary with about 25 percent of the vote, well behind Letlow's 45 percent and Fleming's 28 percent, and failed to qualify for the runoff at all. It was as clear a verdict as Louisiana Republicans could deliver: loyalty to the president's agenda matters, and voting to convict him carries a cost.

With Cassidy out of the picture, the runoff became a contest over who could better claim the mantle of Trump's movement, and it got personal fast. Fleming, who served in the first Trump administration and eight years in the House before becoming state treasurer, argued he had the deeper conservative record and tried to paint Letlow as insufficiently conservative over past comments she made regarding diversity, equity and inclusion policies during her time in higher education administration. Letlow pushed back hard, noting she has spent her time in Congress fighting against the very DEI ideology Fleming accused her of embracing, and her campaign highlighted Fleming's work as a paid consultant for a Washington lobbying firm even while serving as state treasurer. She also emphasized her support for policies protecting women's sports from transgender competitors, a priority that resonates deeply with the conservative base she needed to turn out.

The financial contrast mattered too. Fleming poured more than $11.5 million of his own money into loans to prop up his campaign, while Letlow raised over $5.35 million without loaning herself a dime, a sign of where institutional Republican support in the state was actually flowing. That support was considerable. Governor Jeff Landry endorsed her early and stayed vocal throughout, House Majority Leader Steve Scalise backed her, and Rep. Clay Higgins added his support as well. Trump's endorsement, delivered before Letlow had even formally entered the race, proved decisive in a contest where both candidates spent months trying to out-Trump each other.

Letlow is no stranger to making history. She first came to Congress in 2021 after winning a special election to fill the seat her husband Luke Letlow had been elected to before his death from COVID-19 complications just days before he was set to be sworn in, becoming the first Republican woman ever elected to Congress from Louisiana. A win in November would extend that distinction to the Senate, where Louisiana has never sent a woman of either party. Given that Trump carried Louisiana by roughly 22 points in 2024 and the state hasn't elected a Democrat to the Senate since Mary Landrieu's final term in 2008, Letlow now enters the general election as the prohibitive favorite against Democratic nominee Jamie Davis, a Tensas Parish farmer making his first run at statewide office.

For Louisiana conservatives, the June 27 runoff was about more than one Senate seat. It was a statement that the party's base is unified behind Trump's agenda and unwilling to tolerate wavering from it, even from a sitting senator with two terms of incumbency behind him. Letlow now carries that mandate into November, and if the fall election goes the way most observers expect, Louisiana will send a fighter to the Senate who owes her seat not to Washington insiders but to a grassroots Republican base that turned out to reward loyalty and punish its absence.
